Mechanical integration into the machine

It is proportional to the permissible radial force F
radial
.
The factor of proportionality can be found in sections 4 to 6 in section
"Determining maximum shaft load".
⇒
Using the given formula, determine maximum permissible axial force
F
axial
for your application.
⇒
Make sure that the determined axial force is not exceeded during ope-
rations. Please note the following on this!
Note:
Thermal effects can shift the flanged end of the drive shaft to
the motor housing by up to 0.6 mm. If helical toothed drive pi-
nions or bevel gear pinions are used and mounted directly to
the output shaft, then these changes in the length can lead to
the shifting
•
of position of the axis, if the drive pinions are not axially
fixed to the machine, or
•
a thermally-dependent component of the axial force if
the drive pinions are axially fixed machine side. There is
the danger, in this case, that the maximum permissible
axial force can be exceeded or that the clearance within
the toothing is unacceptably increased.
The use of drive elements with bearings which are connected
to the motor shaft via an axial compensating coupling is thus
recommended.
If permissible radial and axial forces are not exceeded, then the following
applies to nominal bearnig lifespan:

= 30,000 operating hours (calculated per ISO 281, edition 12/1990).

Note:
When mounting drive elements to the motor shaft, do not use
fixed supported bearings, but rather bearings that are simply
supported. The indispensable and existing tolerances genera-
te the application of additional forces to the bearings of the
motor shaft and possibly lead to a drop in service life. If a fixed
type of mounting cannot be avoided, please contact
INDRAMAT!
